A. WYLlE Q g zmmm WINDING HEAD Filed Jan. 31, 1934 Patented May 19, 1936 UNITED STATES PATENT OFFICE 2,o41,1o2 WINDING HEAD Application January 31, 1934, Serial No. '709,226

2 Claims.

This invention relates to improvements in winding heads.

It is customary, where continuous unwinding of the yarn from a number of bobbins is desired, to so Originally wind the yarn upon the bobbins as to leave a portion of the inner end of the yarn package projecting so` that this loose end may be tied to the outer end of the yarn on an -adjoining bobbin. When the yarn on the two bobbins is so connected, it may be withdrawn from the bobbins in an axial direction or over the ends of the bobbins without interruption, the yarn first being completely drawn from the first bobbin and then from the other. Whole series of bobbins may thus be connected for continuous unwinding Operations.

It has been customary to provide special bobbins for this purpose, these bobbins being provided with means for receiving one or two convolutions of the initial end of the yarn before the yarn is passed to the bobbin barrel. such bobbins materially facilitate the operation of forming the loose inner yarn ends as set forth. These bobbins, however, being of special construction necessarily involve additional cost of production as compared with the standard bobbin, and since frequently a large number of such bobbins are required, the expense involved is considerable.

An object of the present invention is to provide means for forming the loose inner ends of yarn that shall be separate from the bobbin, which may then be of standard form, and to this general end, a further object of the invention is to provide a novel form of winding head incorporating the said means either as a fixed or detachable part thereof, as hereinafter set forth.

My invention entirely avoids the necessity for special bobbins, and makes entirely practicable the use of the standard form of bobbin for continuous unwinding Operations, as set forth.

In the attached drawing: p

Figure 1 is a view in perspective of a winding head made in accordance with my invention;

Fig. 2 is a View in perspective of the circumferentially recessed disk forming a detachable part of the winding head shown in Fig. 1;

Fig. 3 is a partial sectional View of the Winding head assembly including a bobbin; and

Fig. 4 is a corresponding View illustrating a modified embodiment of the invention.

With reference to Fig. 1, the bobbin therein illustrated compr'ses the usual stern l having adjacent one end a pulley cylinder 2. In the present instance, this cylinder has at its inner end a reduced extension 3, the function of which will be described hereinafter. The usual spring wires 4 are provided for frictionally retaining a bobbin 5, app lied to the stern I, as shown in Fig. 3.

In accordance with my invention, I provide a disk 6 having a peripheral groove or recess 'I and a central opening 8 adapted to fit the reduced extension 3 of the pulley cylinder 2. When placed upon the extension 3, as shown in Fig. 3, and the bobbin 5 is placed upon the stem I, the disk is confined between the inner end of the bobbin and the end of the pulley 2, and by reason of its peripheral recess 'I provides a means for receiving the initial turns of yarn before the latter is passed to the barrel of the spindle 5, so that when the yarn is completely wound upon said barrel, that portion of the inner end which Originally embraced the disk 6 will form the desired loose end for connection with the outer end of the yarn upon another bobbin.

In this instance, the disk 6 forms a detachable part of the winding head, but this may be made an integral part of the head if desired. In Fig. 4, for example, the disk 8' is Secured to the pulley cylinder 9 by means of screws, and the peripheral edge of the disk 8' in this instance is provided at one side only with a radially projecting flange IU, the peripheral recess cooperating with the head fiange I I of the bobbin when the latter is applied to the stem of the winding head as illustrated.

The practical value of the invention resides in the fact that it obviates the necessity for specially formed bobbins and permits the practical use of standard bobbins for continuous unwinding operations. Furthermore, since the number of winding heads for any machine is relatively small as compared with the total number of bobbins required for many Operations, it is apparent that the device creates a further saving of expense in the substantial reduction in 'the total number of devices required.

It will be understood that I do not wish to limit myself to the particular form of device herein illustrated., and that there may be considerable modification without departure from the invention.

I claim:

1. A winding head for textile spools of the conventional type comprising a barrel having flat-faced disk-like heads, said winding head comprising a spindle, a pulley affixed to the spindle adjacent one nd thereof, and a spool-receiving section of greater length than the spool and provided with means for immobilizing the spool with the spindle, a reduced extension at the inner end of said pulley, and a circumferentially recessed disk of substantially the same diameter as the spool head mounted on said pulley extension and presenting a flat face for abutment With the face of said spool head. i

2. A winding head for textile spools of the conventional type comprising a barrel having fiatfaced disk-like heads, said winding head comprising a spindle, a. pulley aflixed to the spindle adjacent one end thereof, and a spool-receiving section of greater length than the spool and provided with means for immobilizing the spool with the spindle, and a disk of substantially the same diameter as the spool head Secured to the inner end of said pulley and presenting a. fiat face for abutment With the face of said spool head, said disk having a peripheral section of reduced diameter at the side thereof engaged by said spool and forming with the spool head a. circumferential recess.
